feat: Add SitePageSettings - simplified page management system

- New entities: SitePageSettings + SitePageImage (4 fixed pages)
- EF Migration: AddSitePageSettings (SitePageSettings + SitePageImages tables)
- Proto: sitepagesettings.proto with 5 RPCs
- CQRS: GetPageSettings, GetAllPageSettings, SavePageSettings, SavePageImage, DeletePageImage
- gRPC Service: SitePageSettingsService (auto-registered)
- Proto NuGet bumped to 0.0.180
